Question

I wanted to remove type hints from my Clojure source codes, so I tried:

echo "(def ^Integer a 1)" | egrep '\^\w+ '

And it successfully matches the type hint.

Next, I tried:

echo "(def ^Integer a 1)" | sed s/\^\w+//g

however sed does not replace the type hint with empty.

What is wrong with my regex?

Answer 1

You need to enclose the regex in ' and also escape the +:

echo "(def ^Integer a 1)" | sed 's/\^\w\+//g'
